An isoenzyme analysis was performed on 109 individuals from 11 populations of Juniperus excelsa complex collected from Iran. A total of 61 allozymes from five enzyme systems were scored. The mean numbers of bands per presumed isoenzyme, ranged from 2.07 to 3.23. The value of Euclidean distance ranged from 1.920 to 4.411. The average value of Shannon diversity index (H′) estimated for each population ranged from 0.317 in the population sampled from ‘Fasa’ to 1.053 in the population of ‘Golestan’, and the average H′ value for each enzyme system ranged from 0.031 (SOD-3) to 1.670 (PPO-1). To reveal the relationships among these populations, a cluster analysis based on Euclidean distances was performed. The results of the analysis suggest recognizing three taxa in the complex in Iran: Juniperus polycarpos subsp. polycarpos, Juniperus polycarpos subsp. turcomanica, and one cryptic species not recorded from Iran until now. Moreover, the analysis presented, does not confirm the occurrence of J. excelsa in Iran.
